如何申请不等于Linq XName

Question

这是为了获取＆＃34;车辆标签＆＃34;

以外的标签

 document.Descendants(s0 + "Vehicles").Elements().ToList().ForEach(x => x.Add(document.Elements().Where(d => d.Element != s0 + "Vehicles")));

需要从基础xml添加除车辆之外的元素，并尝试将其另存为路径中的新xml文件。

Base Xml是

<?xml version="1.0" encoding="utf-8"?>

输出应该是两个文件

但是我收到了我们无法使用的错误！=运算符 错误2运营商＆＃39;！=＆＃39;不能应用于类型＆＃39;方法组的操作数＆＃39;和＆＃39; System.Xml.Linq.XName＆＃39; c：\ users \ 502556385 \ documents \ visual studio 2012 \ Projects \ SplitXML \ SplitXML \ Program.cs 31 122 SplitXML

Answer 1

您需要使用XName，而不是字符串：

document.Descendants(XName.Get("Vehicles",s0)).Elements().ToList()
.ForEach(x => x.Add(document.Elements().Where(d => d.Name != XName.Get("Vehicles",s0)));

该方法使用以下参数：XName.Get(string tagName,string namespace). 如果s0确实是命名空间（XNameSpace），则需要使用s0.NameSpace来获取字符串名称。
